battery life

[drbveb88]

Simple question for all the experts...

If two different Roms are running the same Kernel, should the battery drain be that much different?

Im running REZRom currently and thinking about switching to Bamf 2.1. i'm sure both roms are smooth and fantastic I just want the one with the best battery life.

Any advice would be great, thanks in advance.

You should get good battery life on either. That is depending on your usage and setup of course.

Battery life with same kernel should not vary too much from ROM to ROM. Depends on how much "stuff" is running in bakground that might be using the battery up. The kernel makes the biggest difference since it controls the whole system. I am personally using Scotts CleanRom Developers Edition (Senseless) and it is great! I get a solid 13+ hours with moderate use (some calls, lots of web, and a few games) and thats on 4G for 11-12 hours of it! If you use wifi you probably could squeeze another hour or 2 out of the battery...

This is on clean rom dev edition. 2 hours screen on time so far with standard battery. I use 3g normally unless I need 4g. I also use juice defender ultimate and keep data off while not in use.

While there are a number of tweaks and apps you can use (like SetCPU) to improve battery life, it's true that the kernel has more to do with battery life than that ROM itself.

Sometimes a rogue app can prevent the cpu from idling or prevent the phone from entering deep sleep mode. This happens on mine occasionally, and you can usually tell from the extended battery graph because the phone will show as awake for large periods of time, even when the screen is off and it should be in sleep mode.
